A Patent in the Civil Engineering Department
The Ph.D. student Riyadh Abdel-Abbas Ali innovated under the supervision of Prof. Dr. Ibtisam Raheem Karim from the Department of Civil Engineering of the University of Technology and in partnership with Prof. Dr. Saleh Issa Khassaf from the College of Engineering at the University of Basra on the topic (Innovative Intelligent Laboratory System to Simulate the Real Water-Structure-Earthquake Interaction Test (RWSEIT) and Its Influence for Dynamic Response of Marine Concrete Structures).
It is considered the first innovation in the field of civil engineering that has the ability to simulate real earthquakes combined with the water forces represented by currents and waves to discover the effect of these forces on the dynamic behavior of sea bridges.
The work included the manufacture of a laboratory channel with a length of (6) meters, a width of (1.5) meters, and a height of (1.25) meters, which is a contains on a (Biaxial Shaking Table) device to represent the real earthquakes and their actual directions (X&Y) and approved in the international codes (ASTM & ACI), and the channel also contains two technologies to generate waves and currents of water with variable characteristics and controlled electronically through an intelligent control system that designed software for this purpose.
The innovative system was registered as an Iraqi patent approved by the American (University of New Mexico) and under the title:
(Innovative Intelligent Laboratory System to Simulate the Real Water-Structure-Earthquake Interaction Test (RWSEIT) and Its Influence for Dynamic Response of Marine Concrete Structures).
Highway and Bridges Engineering branch held a discussion session

One of the most problems that face concrete production in Iraq and various countries in the Middle East is hot weather concreting. For example, in Iraq, the temperature reached 50°C in the summer season, therefore, the construction season is shortened by at least two months (July-August). Several international standards have recommended specific precautionary cooling measures to reach the maximum acceptable temperature of recently mixed concrete, in target to avoid adverse effects on concrete. The main objective of the study is to reveal the effects of cooling via using liquid nitrogen on the soft and hardening properties of concrete as well as the microstructure of hardened concrete. Multiple concrete mixtures with different pozzolanic materials were produced, poured, and cured at high temperatures (40 - 45oC) pointing to uses in hot summer periods in most regions of Iraq. The design of the experiment's approach was followed to evaluate the efficiency of liquid nitrogen in improving the properties of fresh and hardened concrete against other alternatives. Considered independent variables were fly ash, nano-silica, and liquid nitrogen. Pouring concrete at high temperatures weather requires the use of up to 276 liters / m3 of liquid nitrogen to reduce the concrete temperature by 20 degrees Celsius. The results showed that liquid nitrogen considerably improved the whole fresh and hardened properties of concrete mix produced at high temperatures.
